NAPHTHOFLUORESCEIN Chemical Properties,Usage,Production

Uses

Naphthofluorescein is a furin inhibitor.

Uses

Naphtofluorescein is a pH-sensitive fluorescent probe, also used for preparation of labels and enzyme substrates.

Definition

ChEBI: Naphthofluorescein is a member of xanthenes.

in vivo

Naphthofluorescein (compound 19) (100 mg/kg; i.p.; once daily for 5 consecutive days followed by 2 days off for 2 weeks)does not show weight loss or apparent histological abnormalities in the lung, liver, and kidney, or cause cause severe adverse effects for at least 2 weeks in mice^[1].
Naphthofluorescein (compound 19) (100 mg/kg; i.p.; once daily for 5 consecutive days followed by 2 days off for 2 weeks) strikingly suppresses the tumour growth of subcutaneously injected E0771 cells and significantly attenuates tumour growth of MDA-MB-231 and AsPC-1 cells in immunodeficient mice. In turn, naphthofluorescein does not attenuate tumour growth of FIH-1-depleted MDA-MB-231 cells^[1].
Naphthofluorescein (compound 19) (100 mg/kg; i.p.; once daily for 5 consecutive days followed by 2 days off for 2 weeks) suppresses tumour growth in human cancer cells in an FIH-1-dependent manner^[1].

Animal Model:	Male C57BL/6J mice (8 weeks)^[1]
Dosage:	100 mg/kg
Administration:	i.p.; once daily for 5 consecutive days followed by 2 days off for 2 weeks
Result:	Neither showed weight loss or apparent histological abnormalities in the lung, liver, and kidney, or caused cause severe adverse effects for at least 2 weeks in mice.

Animal Model:	Female C57BL/6J mice (E0771) and BALB/c nude mice (HT1080, MDA-MB-231, and AsPC-1) (6 weeks)^[1]
Dosage:	100 mg/kg
Administration:	i.p.; once daily for 5 consecutive days followed by 2 days off for 2 weeks
Result:	Strikingly suppressed the tumour growth of subcutaneously injected E0771 cells and significantly attenuated tumour growth of MDA-MB-231 and AsPC-1 cells in immunodeficient mice. In turn, naphthofluorescein did not attenuate tumour growth of FIH-1-depleted MDA-MB-231 cells.
